Cross-site scripting (XSS) vulnerability in the Taxonews module before 6.x-1.2 and 7.x-1.x before 7.x-1.1 for Drupal allows remote authenticated users with the "administer taxonomy" permission to inject arbitrary web script or HTML via a term name in a block.

Taxonews module for Drupal is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote authenticated attacker could exploit this vulnerability using the term names to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
